WEBVTT 1 00:00:00.000 --> 00:00:03.150 So the next section because, you know, it's 2 00:00:03.180 --> 00:00:07.230 basically Star Wars, which you'll find out drawbacks a lot 3 00:00:07.230 --> 00:00:09.330 of investments in the technology, especially under the 4 00:00:09.330 --> 00:00:14.100 diagnostics. The big major facilities were coming online. 5 00:00:14.460 --> 00:00:18.720 And of course, there was a British invasion and you know, 6 00:00:18.900 --> 00:00:24.480 falling in the Beatles was the May started another one. So, so 7 00:00:24.510 --> 00:00:28.320 and this session will be chaired by Dustin overdue Dustin, 8 00:00:28.710 --> 00:00:29.160 British 9 00:00:35.220 --> 00:00:38.790 there wasn't, there wasn't well, I'm an American, but the throw 10 00:00:38.790 --> 00:00:42.000 is a no vote. So Scotland is still formally part of Great 11 00:00:42.000 --> 00:00:42.240 Britain, 12 00:00:43.230 --> 00:00:45.810 Ireland and Great Britain. Right. Yeah. So, 13 00:00:46.080 --> 00:00:50.040 you know, I, I think the Star Wars program, as you point out 14 00:00:50.040 --> 00:00:54.810 is really major technology driver. And really bigger than 15 00:00:54.810 --> 00:00:58.200 that it captured the imagination of the world and drove a lot of 16 00:00:58.200 --> 00:01:03.180 technology. In the 1980s, across the board, I know, I was aware 17 00:01:03.180 --> 00:01:05.610 of it at some of the earliest science that I actually was 18 00:01:05.610 --> 00:01:09.510 aware of, I was, you know, five to 10 years old at that point in 19 00:01:09.510 --> 00:01:15.180 living in a family that doing Star Wars programs in our arm. 20 00:01:15.870 --> 00:01:19.800 And so for me, it was very influential in getting me into 21 00:01:19.800 --> 00:01:22.380 this field and learning about Livermore and learning about the 22 00:01:22.380 --> 00:01:29.550 program. Even Ella Lee had some some pretty solid ties into that 23 00:01:29.550 --> 00:01:35.250 program, that Strategic Defense Office stdio funded LLP in a few 24 00:01:35.310 --> 00:01:39.690 areas, as part of the sowers program, and Bill Donaldson was 25 00:01:39.690 --> 00:01:42.900 one of the Knights at that time, brought that to my attention. 26 00:01:43.980 --> 00:01:47.010 And, you know, if you really scour the archives, you'll 27 00:01:47.010 --> 00:01:50.310 actually find a patent on superconducting switches for 28 00:01:50.310 --> 00:01:53.700 post power that basically resulted out of that work with 29 00:01:54.240 --> 00:01:59.790 stdio. You know, in fact, LLC hosted a workshop on Star Wars 30 00:01:59.790 --> 00:02:04.290 and stdio, back in 1988. And there was apparently a couple 31 00:02:04.290 --> 00:02:07.410 others that I couldn't dig out of the archive. So So there's, 32 00:02:07.500 --> 00:02:11.100 there's some, there's some connection to lled. But really, 33 00:02:11.100 --> 00:02:15.330 this period is not about LSD. It's about Mike, and his 34 00:02:15.330 --> 00:02:18.600 contributions to the National Program and the emergence of the 35 00:02:18.600 --> 00:02:22.260 large facilities that paved the way for ignition, which then 36 00:02:22.260 --> 00:02:27.900 also brings in the British invasion. So before we start it, 37 00:02:27.900 --> 00:02:32.520 go through and introduce the panels panel and have you folks 38 00:02:32.520 --> 00:02:36.360 a little bit on yourself, I think the panel members are 39 00:02:36.360 --> 00:02:39.180 really some legends in their own right. And I don't know that 40 00:02:39.180 --> 00:02:43.320 everybody of the younger generation knows who you are. 41 00:02:43.320 --> 00:02:47.730 And so maybe just for the first part, tell us who you are and 42 00:02:47.730 --> 00:02:51.870 how you came to get involved with Mike and that if you 43 00:02:51.870 --> 00:02:56.460 haven't already had that opportunity. And so let's let's 44 00:02:56.460 --> 00:02:59.580 start with that. The panel members, I guess they're up 45 00:02:59.580 --> 00:03:02.280 there. Okay. That's good. So, Joe, do you want to kick that 46 00:03:02.280 --> 00:03:04.740 off? I know you've had a chance to talk a little bit, but maybe 47 00:03:05.100 --> 00:03:07.560 give us a little bit of background there. And maybe a 48 00:03:07.560 --> 00:03:14.040 story about when? When you Yeah, when you met Mike or? Yeah. 49 00:03:15.000 --> 00:03:21.210 Yeah, sure. Can. Can I share my screen? Yeah, give me one second 50 00:03:21.210 --> 00:03:22.440 how the engineer 51 00:03:22.740 --> 00:03:25.200 can share, but I can't do it with okay. 52 00:03:29.010 --> 00:03:37.290 So I want to talk about the know that epoch. Yeah. And I've 53 00:03:37.290 --> 00:03:42.240 actually got quite a few things to say, Dustin. So how do you 54 00:03:42.240 --> 00:03:48.540 want to handle this? Let's do introductions 55 00:03:48.540 --> 00:03:51.240 first, so we get all the panelists introduced, and then 56 00:03:51.270 --> 00:03:54.120 I'll give you plenty of time. We got a good hour and we're gonna 57 00:03:54.120 --> 00:03:55.260 go through okay, but 58 00:03:58.170 --> 00:04:01.830 let's, let's not share screen now then. Okay. So, as I said, I 59 00:04:01.830 --> 00:04:04.710 met Mike in 1988. at the Ecole 60 00:04:06.180 --> 00:04:13.530 Polytechnique at the Ecole Polytechnique in Panama. So I'm 61 00:04:13.530 --> 00:04:26.880 fixed actually is this too but only recently and I he recruited 62 00:04:26.880 --> 00:04:33.480 me when he handed me through to me to the Lawrence Livermore Lab 63 00:04:33.870 --> 00:04:38.100 with a clearance I had a UK clearance and as probably that 64 00:04:38.100 --> 00:04:38.790 caused some 65 00:04:38.790 --> 00:04:43.830 consternation is quite famous. We were clearance people because 66 00:04:45.270 --> 00:04:49.410 they went ahead with a Q clearance before I was a eu US 67 00:04:49.410 --> 00:04:54.600 citizen I think and work for him on Nova and I have a lot to say. 68 00:04:55.020 --> 00:05:02.280 Being that I have a lot to say about that. Sure, thanks. So 69 00:05:03.870 --> 00:05:04.380 Melissa, 70 00:05:05.430 --> 00:05:08.610 is on line with us too. It looks like do you want to take a 71 00:05:08.610 --> 00:05:11.790 chance? And yeah, there you are great. Good to see you. And you 72 00:05:11.790 --> 00:05:15.300 want to unmute so we can hear you and give us a chance to tell 73 00:05:15.300 --> 00:05:24.210 us about yourself a little bit. still muted Melissa. Sorry. I 74 00:05:24.210 --> 00:05:30.450 muted Melissa. Yeah, hold on one second, and either hold spacebar 75 00:05:30.450 --> 00:05:31.380 down or unmute. 76 00:05:38.430 --> 00:05:42.270 I can, we can hear you Alyssa. 77 00:05:43.350 --> 00:05:47.700 Great. Well, good. Good to be here. Celebrating Mike, he 78 00:05:48.180 --> 00:05:52.770 certainly deserves a lot of kudos for his contributions to 79 00:05:52.770 --> 00:05:57.990 the ICF program over the years. So my history is in 1984, I 80 00:05:57.990 --> 00:06:01.470 joined the Los Alamos as a secondary designer and 81 00:06:01.470 --> 00:06:08.790 underground test program, got some experience, got experience 82 00:06:08.790 --> 00:06:14.040 designing underground test experiments and for Nevada, and 83 00:06:14.610 --> 00:06:18.510 very much was steeped in the culture of the weapons program, 84 00:06:19.620 --> 00:06:25.050 where it was very important. Equally important to be able to 85 00:06:25.320 --> 00:06:30.930 send the data through computation. In in the nuclear 86 00:06:30.930 --> 00:06:33.870 test program, there were very, very strong collaborations 87 00:06:33.870 --> 00:06:38.100 between theoretical people like myself, designers like myself, 88 00:06:39.060 --> 00:06:43.980 the people who were to building the weapons, and also the 89 00:06:44.040 --> 00:06:48.570 computational scientists. One disappointment I had in the in 90 00:06:48.570 --> 00:06:53.040 my time in the nuclear weapons program was the lack of fidelity 91 00:06:53.040 --> 00:06:58.380 and a lot of the computational tools. And so in my time I spent 92 00:06:58.770 --> 00:07:02.610 in the underground test program, I really focused on beefing up 93 00:07:02.640 --> 00:07:06.360 the ability to calculate some of the experiments we were working 94 00:07:06.360 --> 00:07:12.900 on. And as I transitioned into the ICF program in 1987, I took 95 00:07:12.930 --> 00:07:16.620 those foundations with me the importance of having a well 96 00:07:16.620 --> 00:07:21.120 rounded program focused on design, experimentation and 97 00:07:21.120 --> 00:07:25.320 fabrication, as well as the extreme importance and 98 00:07:25.320 --> 00:07:29.760 collaboration to move things forward. And in particular, 99 00:07:29.760 --> 00:07:36.540 bringing into the ICF program, very strong adherence to being 100 00:07:36.540 --> 00:07:40.800 able to step up the ability to calculate what we could when it 101 00:07:40.800 --> 00:07:45.660 came to, in the case of Los Alamos formed designs, it was a 102 00:07:45.660 --> 00:07:49.680 very hard time to be part of the ICF program at Los Alamos, 103 00:07:49.710 --> 00:07:53.790 because we were very much still suffering from the demise of the 104 00:07:53.790 --> 00:08:00.360 co2 laser de or reputation, or focused on KERS lasers at the 105 00:08:00.360 --> 00:08:05.280 time, and our program was stumbling along, underfunded. 106 00:08:05.760 --> 00:08:11.310 And stumbling, I guess, is probably the nicest way to put 107 00:08:11.310 --> 00:08:18.540 it. So as a young designer in ICF programs, in the late 80s, I 108 00:08:18.540 --> 00:08:23.850 saw that there was a void in leadership. And I was happy to 109 00:08:23.850 --> 00:08:27.810 see strong leaders like Steve younger come along, and try to 110 00:08:27.810 --> 00:08:32.850 push the program forward. But unfortunately, it was not in a 111 00:08:32.850 --> 00:08:36.360 collaborative way, which I would have chosen had I been leading 112 00:08:36.930 --> 00:08:43.050 initially. Because Steve was very much a my way or the 113 00:08:43.050 --> 00:08:47.910 highway kind of guy at that point in his career. And so it 114 00:08:47.910 --> 00:08:52.860 was, it was exciting. But it was also you could see stumbling 115 00:08:52.860 --> 00:08:56.940 blocks ahead of the Los Alamos collaboration. When I first met 116 00:08:56.940 --> 00:09:00.780 Mike, he was actually working more on the laser side than on 117 00:09:00.780 --> 00:09:06.480 the target side of things. And it was through interactions with 118 00:09:06.780 --> 00:09:12.330 Steve younger that I came to understand Mike's ways, some of 119 00:09:12.360 --> 00:09:16.590 which were pleasing to some of us at Los Alamos and some which 120 00:09:16.620 --> 00:09:22.740 were frustrated. Others that love, shall I say, so, but as a 121 00:09:22.740 --> 00:09:26.940 as a young person in the ICF program, it was incredible to 122 00:09:26.940 --> 00:09:33.390 learn about not just the physics of what was going on in ICF, and 123 00:09:33.390 --> 00:09:36.660 the fantastic diagnostics that Joe and his people were pulling 124 00:09:36.660 --> 00:09:40.650 out, pulling off at NOVA, but also the political side from 125 00:09:40.650 --> 00:09:47.070 both Mike and what it was required to be successful in 126 00:09:47.100 --> 00:09:49.080 selling the next generation facility. 127 00:09:51.960 --> 00:09:53.250 That's great. Thank you. And 128 00:09:53.280 --> 00:09:55.590 we'll have some time to come back and tell some other 129 00:09:55.590 --> 00:09:59.730 stories. Chris, Christina, you want to start out and introduce 130 00:09:59.730 --> 00:10:00.960 yourself? Hello and welcome. 131 00:10:01.770 --> 00:10:05.490 Yeah, Dustin, thank you. Can you hear me? Okay? That was great. 132 00:10:05.820 --> 00:10:08.310 All right, great. Awesome. Well, hey, it's wonderful to see you 133 00:10:08.310 --> 00:10:12.420 all. And Mike, it's great to see you. And congratulations on your 134 00:10:12.420 --> 00:10:14.940 retirement. We'll talk more. But yeah, I mean, and I've just the 135 00:10:14.940 --> 00:10:19.050 watchwords of your work have been, always follow the lead of 136 00:10:19.050 --> 00:10:21.180 the best science and be collaborative. That's been 137 00:10:21.540 --> 00:10:24.300 tremendously important for the program. So thank you for that 138 00:10:24.300 --> 00:10:27.030 and your leadership. We'll get to that. So yeah, quickly intro 139 00:10:27.030 --> 00:10:29.700 my background I gret actually grew up my start with the 140 00:10:29.700 --> 00:10:33.030 program commenced in 1980. In terms of institutional 141 00:10:33.030 --> 00:10:35.550 affiliation, I actually graduated from the U of R then 142 00:10:35.550 --> 00:10:38.280 although I didn't work at La during that time. During that 143 00:10:38.280 --> 00:10:40.860 time, I spent most of my undergrad research with Dave 144 00:10:40.860 --> 00:10:44.040 Douglas and physics on gravity waves. And I think he was still 145 00:10:44.040 --> 00:10:48.480 around, of course, that was not with Frommers, but with silicon 146 00:10:48.480 --> 00:10:50.610 bars and Haiku, you know, basically looking at the 147 00:10:50.610 --> 00:10:54.870 resonant excitation. But after graduating from the U of R went 148 00:10:54.870 --> 00:10:58.020 to grad school at Princeton, I actually started out in the same 149 00:10:58.020 --> 00:11:01.140 lab that Mike did his PhD work in which was the electric 150 00:11:01.140 --> 00:11:07.890 propulsion lab and led by a guy named Dean Bob John. And that 151 00:11:07.890 --> 00:11:11.130 was very interesting times there. But then I quickly 152 00:11:11.130 --> 00:11:13.470 switched over to the plasma physics lab because I was more 153 00:11:13.470 --> 00:11:17.370 interested in sort of the Plasma Physics line, where I joined the 154 00:11:17.370 --> 00:11:22.380 X ray laser group in 1981. It was led by Professor Shimon sick 155 00:11:22.380 --> 00:11:25.950 caver at Princeton who's still there. Got to know Mike during 156 00:11:25.950 --> 00:11:28.770 that time, because at that time, the X ray laser world was 157 00:11:28.770 --> 00:11:32.580 dominated by Livermore. The UK is Josiah with my key and 158 00:11:32.580 --> 00:11:38.190 colleagues, France piers gelei Sandhya. Keith, great to see 159 00:11:38.190 --> 00:11:41.700 you. And also physics internationals, I recall, Dr. 160 00:11:41.700 --> 00:11:45.330 Dini knows them well stick them long. Another figure from the 161 00:11:45.330 --> 00:11:49.230 past but very accurate extra lasercut. Got to know Mike 162 00:11:49.230 --> 00:11:54.690 there. And he recruited me to to Livermore in 1986, which is 163 00:11:54.690 --> 00:11:58.410 where it came after I got my PhD. Just a quick comment on X 164 00:11:58.410 --> 00:12:00.810 ray lasers, which we can talk about later. I think it's 165 00:12:01.170 --> 00:12:04.020 important to recognize that the X ray laser program was really 166 00:12:04.020 --> 00:12:07.980 the first major or one of the initial major efforts between 167 00:12:07.980 --> 00:12:10.740 the weapons program and the laboratory experiments program, 168 00:12:10.740 --> 00:12:14.460 which really got the stockpile stewardship connection between 169 00:12:14.610 --> 00:12:18.990 lasers. And the weapons program goes an enormous step not just 170 00:12:18.990 --> 00:12:24.300 for X ray lasers, but also for the nation in terms of getting a 171 00:12:24.330 --> 00:12:26.610 you know, an above ground testing capability with lasers 172 00:12:26.610 --> 00:12:30.720 doing EGD physics, so anyway, can't deliver on 86 Recruit 173 00:12:30.720 --> 00:12:35.580 recruited by Mike you know, work with him there. I really enjoyed 174 00:12:35.580 --> 00:12:39.090 that for a while. 95 I actually want to add, you know, thanks to 175 00:12:39.090 --> 00:12:44.250 Mike and Joe. I went to DOE as an advisor in the ICF program 176 00:12:44.250 --> 00:12:47.130 office, I stayed there working with Dave Crandall, de Great to 177 00:12:47.130 --> 00:12:51.480 see you and others for a number of years, led a number of 178 00:12:51.480 --> 00:12:54.660 programs including ICF construction for a short time 179 00:12:54.660 --> 00:13:01.980 actually was at the department to through essentially 2007 came 180 00:13:02.010 --> 00:13:07.740 back to Livermore and that and then served at the as the 181 00:13:07.740 --> 00:13:10.470 director of the nephews rockets, essentially working on the NIF 182 00:13:10.470 --> 00:13:14.490 science, fundamental science connection until in 2014, and 183 00:13:14.490 --> 00:13:16.740 went to Washington State University, which is where you 184 00:13:16.740 --> 00:13:19.980 can see at the top is Vice President for Research, or I am 185 00:13:19.980 --> 00:13:23.610 now and I continue collaborating with Mike and Dr. DE Anita. I 186 00:13:23.610 --> 00:13:27.900 say that because there's a lot of Chris's in the room this day, 187 00:13:28.380 --> 00:13:31.200 working in collaboration with the Institute shock physics here 188 00:13:31.200 --> 00:13:33.630 at WSU and you are so great to see so. 189 00:13:35.160 --> 00:13:36.450 Okay, thank you, Chris. Great, 190 00:13:36.450 --> 00:13:41.220 great introduction and Morty. Are you Rosen you. Great to see 191 00:13:41.220 --> 00:13:44.310 you. Do you want to have a chance here to tell us about 192 00:13:45.180 --> 00:13:48.120 yourself and your introductions with Mike in the early days? 193 00:13:48.570 --> 00:13:49.230 Sure. Great 194 00:13:49.230 --> 00:13:54.540 to see everybody. I came to the lab in 76 and as Livermore from 195 00:13:54.570 --> 00:13:58.200 from Princeton Plasma Physics Lab. I came for the reason Mike 196 00:13:58.230 --> 00:14:01.710 said a few minutes ago, I talked him back once it's built, you're 197 00:14:01.710 --> 00:14:05.880 stuck. A laser is just the energy source and you can put a 198 00:14:05.880 --> 00:14:12.090 new token back in front of the laser every single day. And that 199 00:14:12.090 --> 00:14:15.810 was a great choice and 46 years later, I'm still working full 200 00:14:15.810 --> 00:14:22.050 time and enjoying that very concepts. I want to just build a 201 00:14:22.050 --> 00:14:27.030 bridge back to our first section this morning. Which will be an 202 00:14:27.030 --> 00:14:30.990 introduction of how I got into X ray lazing because I started out 203 00:14:31.350 --> 00:14:37.050 in with John knuckles group I was recruited by climax to and I 204 00:14:37.050 --> 00:14:42.360 started with the exploding pushers. But we did have the IR 205 00:14:42.870 --> 00:14:49.140 catastrophe as Mike and Joe pointed out and we started 206 00:14:49.140 --> 00:14:52.620 something new which is since the targets weren't working 207 00:14:52.620 --> 00:14:55.740 properly, we decided to cut the whole round in half along the 208 00:14:55.740 --> 00:15:00.000 waist and that in that way you could see inside the target and 209 00:15:00.000 --> 00:15:05.430 Not just outside, and you put a slab up against a hole in the 210 00:15:05.430 --> 00:15:08.190 back wall of a half round. And you could see what was 211 00:15:08.190 --> 00:15:12.090 happening. And indeed, we saw the preheats that the electrons 212 00:15:12.090 --> 00:15:17.160 were happening that we're causing. That led to a whole 213 00:15:17.160 --> 00:15:20.460 concept of what we now call high energy density, because you 214 00:15:20.460 --> 00:15:23.280 didn't just have to put the slab that the capsule was you could 215 00:15:23.280 --> 00:15:26.310 put a piece of gold and watch the X rays come through and 216 00:15:26.310 --> 00:15:31.020 measure opacity, et cetera, et cetera, which is the great field 217 00:15:31.020 --> 00:15:38.250 of hGD. We have today, hydro etc. Now, a colleague, a late 218 00:15:38.250 --> 00:15:41.580 colleague, Gabe zonkey, and myself, basically proposed to 219 00:15:41.580 --> 00:15:46.770 the weapons weapons program, an entire book full of ideas of 220 00:15:46.770 --> 00:15:52.680 what to do for hGD to help them. But the weapons program and Mike 221 00:15:52.740 --> 00:15:57.480 Mike talked about North and South Livermore. They were busy 222 00:15:57.480 --> 00:16:01.440 doing lots of tests, so they weren't really interested. So 223 00:16:02.340 --> 00:16:05.820 they weren't interested in what ABI had to offer and the laser 224 00:16:05.820 --> 00:16:09.420 program, he's interested in ICF. They weren't interested in what 225 00:16:09.420 --> 00:16:13.080 he and I had to offer. It kind of felt like an orphan for a 226 00:16:13.080 --> 00:16:17.940 while. But aw II had very few tests, they were super 227 00:16:17.940 --> 00:16:22.620 interested in doing laser hGD. And Brian Thomas and company 228 00:16:22.650 --> 00:16:27.030 there were kind of my soulmates because they were interested in 229 00:16:27.030 --> 00:16:32.460 hGD. So in that background, Star Wars was happening at the lab. 230 00:16:32.880 --> 00:16:37.170 And Peter Hagel, Stein, who had certain calculational tools, 231 00:16:37.890 --> 00:16:41.640 wanted to exercise them on laboratory experiments. And he 232 00:16:41.640 --> 00:16:46.020 had some ideas for the transitions that an x ray laser 233 00:16:46.020 --> 00:16:51.870 would make in the laboratory driven by our glass lasers. So 234 00:16:51.870 --> 00:16:54.810 John knockos, stuck his head in my office one day and asked me 235 00:16:54.810 --> 00:16:59.820 if I could spend 20% of my time helping Peter, with the design 236 00:16:59.820 --> 00:17:05.430 part. And the first meeting I had with Peter and our boss at 237 00:17:05.430 --> 00:17:10.500 the time, for the Star Wars side of the house, I learned 238 00:17:10.500 --> 00:17:14.400 something terrible, the thing I learned was, we had no designs 239 00:17:14.430 --> 00:17:21.630 whatsoever for the X ray. And so 20 20% of my time literally 240 00:17:21.630 --> 00:17:27.450 became 200% of my time. I slept on the floor of my office in a 241 00:17:27.450 --> 00:17:32.490 sleeping bag many nights, because the laser was going to 242 00:17:32.490 --> 00:17:36.840 shut down in the summer, and we had to get shots done. So no 243 00:17:36.840 --> 00:17:41.400 ideas for target design, who should walk into my office. But 244 00:17:41.400 --> 00:17:46.590 our honoree, Mike Campbell, Mike is amazing in his ability to go 245 00:17:46.650 --> 00:17:50.220 up and down the hallways, pop his head and know exactly what 246 00:17:50.220 --> 00:17:54.540 people are doing. And he's the great connector. And Mike said, 247 00:17:54.540 --> 00:17:58.980 you know, we're doing these LPI experiments with this new 248 00:17:58.980 --> 00:18:03.750 platform and exploding pusher, which, which explodes and makes 249 00:18:03.750 --> 00:18:10.680 a nice shallow gradients. So you could actually be a good medium 250 00:18:10.680 --> 00:18:15.540 for having the extra laser propagate. And I pursued that 251 00:18:15.540 --> 00:18:18.810 calculation only. And that is in fact the target design that 252 00:18:19.620 --> 00:18:23.280 succeeded in the first laboratory X ray laser. And I'm 253 00:18:23.280 --> 00:18:26.970 very proud and always will be proud that Mike and I are the CO 254 00:18:26.970 --> 00:18:32.940 patent holders of that design. So that's how we come from the 255 00:18:32.940 --> 00:18:38.100 first section of our talk this morning to dissection on on X 256 00:18:38.100 --> 00:18:40.740 ray lasers. I'll stop there for now. 257 00:18:42.480 --> 00:18:44.730 Great, thanks, Marty. That's great. That's fun to hear. 258 00:18:45.180 --> 00:18:48.870 It's neat to hear the connection to the X ray lasers. Both you 259 00:18:48.870 --> 00:18:52.440 and Chris brought up and let me pivot a little bit that back to 260 00:18:52.440 --> 00:18:55.950 Joe and give Joe an opportunity to tell some of the early days 261 00:18:55.950 --> 00:18:59.160 stories and maybe also I'm interested from all of you about 262 00:18:59.160 --> 00:19:02.100 you know, what, what do you remember is Mike's earliest 263 00:19:02.100 --> 00:19:06.300 contribution to the program you know, it could go either way and 264 00:19:06.300 --> 00:19:08.790 positive one or negative one I mean I'm sure there's there's 265 00:19:08.790 --> 00:19:11.550 both of them out there that that might be fun to talk about. So 266 00:19:11.700 --> 00:19:15.210 think about that and maybe weave it into your stories as you go 267 00:19:15.210 --> 00:19:24.870 forward. So So Joe, do you want to pick that up somehow you're 268 00:19:24.870 --> 00:19:39.090 muted we don't hear you Joe look muted on there hear you duel 269 00:19:44.880 --> 00:19:45.540 Okay, can you hear 270 00:19:45.540 --> 00:19:57.390 me now? Okay. I'd like to talk about the Nova epoch for a 271 00:19:57.390 --> 00:19:57.840 while. 272 00:19:59.580 --> 00:20:11.310 Um, Mike led that for 1015 years and during that epoch, he was 273 00:20:11.310 --> 00:20:18.180 also the leader for a short time of the laser technology program. 274 00:20:19.980 --> 00:20:25.710 And the bottom line on Nova and beam lead, which was one of the 275 00:20:27.060 --> 00:20:35.550 proof of principle of the five wonders of NIS was that we, 276 00:20:35.640 --> 00:20:42.240 Mike, as the leader established the technical basis in terms of 277 00:20:42.240 --> 00:20:46.500 target shooting, and the laser technology basis that enabled 278 00:20:48.000 --> 00:20:55.410 enabled the review committees and there were many of them, in 279 00:20:55.410 --> 00:20:59.640 particular, the exact committee nourisher confinement fusion 280 00:20:59.670 --> 00:21:04.410 Advisory Committee, which met seven or eight times in about 281 00:21:04.410 --> 00:21:11.790 five years, and then the national, the NIS committee, to 282 00:21:11.790 --> 00:21:16.260 recommend going ahead when death and this was time urgent, it 283 00:21:16.260 --> 00:21:21.510 wasn't obvious at the time, but the great progress Z made wire 284 00:21:21.510 --> 00:21:26.310 arrange that had happened. Mike has told me many times and we 285 00:21:26.310 --> 00:21:28.680 all believe in that that happened a year or two earlier, 286 00:21:29.550 --> 00:21:33.300 we probably wouldn't have gone ahead with Nick, because of 287 00:21:33.300 --> 00:21:38.460 Beamer and the target shooting program, Nick went ahead. And 288 00:21:38.460 --> 00:21:42.600 that is, that's a great achievement. And Mike is the one 289 00:21:42.600 --> 00:21:47.340 person in particular, the leader and the person who made that 290 00:21:47.370 --> 00:21:50.700 happen. Thank you very much, Mike. And it was a great 291 00:21:50.700 --> 00:21:57.600 privilege working with you during that period. So let me 292 00:21:57.600 --> 00:22:05.760 talk a little bit about Nova. I would like to share the screen 293 00:22:05.760 --> 00:22:08.850 and otherwise I will have to I won't be able to show pictures. 294 00:22:09.540 --> 00:22:14.820 But none other than from either about 19 83,000 to the year 295 00:22:14.820 --> 00:22:24.360 2000. During that period, the British invasion happened. 296 00:22:26.100 --> 00:22:29.370 Joe Joe you're in share you Joe you can share your screen you 297 00:22:29.370 --> 00:22:32.100 have something to share there Go Go ahead, you should be able to 298 00:22:42.810 --> 00:22:44.190 you have to give them permission there 299 00:22:47.910 --> 00:22:50.280 is a green button at the bottom that says share. 300 00:22:52.380 --> 00:23:03.480 Five, five, validate the event and access. Oh. Okay, well. Now 301 00:23:03.480 --> 00:23:07.680 that was one of the best laser facilities ever and it certainly 302 00:23:07.680 --> 00:23:13.230 in retrospect. During that period, Mike took the lead and 303 00:23:13.230 --> 00:23:18.180 recruiting the British Invasion, so I will rattle off the names 304 00:23:18.180 --> 00:23:21.720 now. But it wasn't only Livermore. It was also 305 00:23:21.930 --> 00:23:28.020 Rochester. So very much is the first vote Chester. Actually, 306 00:23:28.080 --> 00:23:31.620 probably before Mike Stein here, Marty Richardson and Steve 307 00:23:31.620 --> 00:23:36.540 Paxton. Steve is still there, of course. And then as part of the 308 00:23:36.720 --> 00:23:40.980 mic instigated British Invasion just in what was there for a 309 00:23:40.980 --> 00:23:45.720 year or two. Dave as in Bradley was recruited there in about 310 00:23:45.720 --> 00:23:55.890 1986, Ricardo etheline and about 1988 and then Richard town and 311 00:23:56.580 --> 00:24:03.900 Nielsen Rochester, seven, seven or eight people from Britain, 312 00:24:04.530 --> 00:24:09.720 and then at Livermore. I was recruited in 19, the end of 19. 313 00:24:09.720 --> 00:24:16.170 Agency, I suppose the farmer by Brian as in McAllen. Jonathan 314 00:24:16.170 --> 00:24:21.120 has was there for a short time in the mid 80s. Nino as in 315 00:24:21.120 --> 00:24:27.630 Landon was recruited about 1989. Badly came, Bradley came to 316 00:24:27.630 --> 00:24:37.590 Livermore about 1919 94. Mike key recruited in 1996. John 317 00:24:37.590 --> 00:24:41.970 Edwards, recruited by the following Maudie and Mike and I 318 00:24:41.970 --> 00:24:50.640 had a hand in that about 1997 Andy McKenna in 1999, which a 319 00:24:50.640 --> 00:24:56.430 town came to live along I'm not sure the exact day look and see 320 00:24:56.640 --> 00:25:03.480 and then more recently, pick one Hohenberg Pataky Nagel and hall 321 00:25:03.480 --> 00:25:10.230 so there were a large number of Britons and British people I 322 00:25:10.230 --> 00:25:14.460 have not mentioned and it is on the view graph. Chris as in 323 00:25:14.460 --> 00:25:17.880 Dini, Chris Dini came from Imperial College, I think he 324 00:25:17.880 --> 00:25:22.350 went to Pei first and he went to Sandia. recruited by Dylan, I 325 00:25:22.350 --> 00:25:26.850 think, Daniel, and the early 90s. And of course, Mike 326 00:25:27.660 --> 00:25:31.890 mentioned Hector borders. And part of this was to 327 00:25:37.500 --> 00:25:44.010 make the make the country they go to richer, don't. And that 328 00:25:44.010 --> 00:25:50.640 was the kind of bilbies so we might achievements in the Novi 329 00:25:50.970 --> 00:25:56.700 epoch, recruiting new staff. Between us we increase the shot 330 00:25:56.700 --> 00:26:02.250 rate to about 1400 shots a year at peak. And so a little while, 331 00:26:02.850 --> 00:26:08.070 I used to like to tease Bob McCrory that you still haven't 332 00:26:08.070 --> 00:26:11.730 done as many shots in a year as we have done on no but now that 333 00:26:12.030 --> 00:26:14.760 only lasted until about 1996. 334 00:26:22.170 --> 00:26:28.530 I had worked with Brian Thomas as more dementia and and and the 335 00:26:28.530 --> 00:26:32.430 father weapon six of those is Brian Thomas. My opinion and 336 00:26:32.430 --> 00:26:38.430 probably more use opinion. And what we did on Nova was we 337 00:26:38.430 --> 00:26:44.160 introduced weapons technical Nova, about the mid 80s. Now 338 00:26:44.190 --> 00:26:48.810 this was not a particularly popular move with the Nitin with 339 00:26:48.810 --> 00:26:54.660 the Nova. Well, their laser program management. Mike and I 340 00:26:54.660 --> 00:26:58.920 recall being summoned by one of the laser programs may say you 341 00:26:58.920 --> 00:27:02.700 will not spend any more shots on Nova, or weapons physics, I 342 00:27:02.700 --> 00:27:07.410 forget who said that, Mike, you can probably remind them. And 343 00:27:07.410 --> 00:27:09.660 we've learned this and there were two particular examples. 344 00:27:09.660 --> 00:27:13.380 One was on hydrodynamic instabilities, the other one was 345 00:27:13.380 --> 00:27:18.810 on opacities. And in the end, in 1999, most of the shots on over 346 00:27:19.110 --> 00:27:24.210 were for weapons. We introduced the university use of NOVA 347 00:27:24.210 --> 00:27:28.440 program, which spent about 10 or 15% of the shop, or a 348 00:27:28.440 --> 00:27:33.720 competitively run program. Yeah, that's kind of part of the idea 349 00:27:33.720 --> 00:27:41.280 of the Omega laser you're having on during this period. And then 350 00:27:43.440 --> 00:27:49.470 it's moldy already mentioned. Mike, and others, won the Dawson 351 00:27:49.470 --> 00:27:52.500 Award, which which was the Excellence in plasma physics is 352 00:27:52.500 --> 00:27:56.550 a time of war for the love barteri X ray laser, and then in 353 00:27:56.550 --> 00:28:03.510 particular, I think we knew when to shut it down. We decided to 354 00:28:03.510 --> 00:28:10.710 shut it down in the year 2000. But we didn't used to talk about 355 00:28:10.710 --> 00:28:15.060 succession plans at the time, but we we got omega ready to 356 00:28:15.060 --> 00:28:19.650 learn. So we did an experiment on omega, showing that we can 357 00:28:19.650 --> 00:28:22.080 measure the temperature of hormones on omega with all the 358 00:28:22.080 --> 00:28:25.890 standard stuff that we used on Nova and then we shut Nova down 359 00:28:26.460 --> 00:28:34.200 to focus our efforts on the NIF. Now, as I said in the 90s, might 360 00:28:34.290 --> 00:28:38.970 lead the laser technology programs there are five wonders 361 00:28:38.970 --> 00:28:45.600 of NIF multisegment amplifiers plasma electronic pocket cell 362 00:28:47.640 --> 00:28:56.700 deformable mirrors I should remind you views on my view 363 00:28:56.700 --> 00:29:02.430 class you can't see the wonders of nipple encapsulated in the 364 00:29:02.430 --> 00:29:08.760 bailiff. Okay, remind you who ran the beam that it was Jack as 365 00:29:08.760 --> 00:29:16.260 in Campbell was the guy and Mike and I interviewed Bruno for his 366 00:29:16.290 --> 00:29:26.070 job on the south on on the last importer of Paris in Idaho 1980. 367 00:29:27.240 --> 00:29:33.090 But the beam that showed that Nick was ready in a laser 368 00:29:33.090 --> 00:29:38.640 technic technology sense. And then during this period as 369 00:29:38.640 --> 00:29:42.630 Melissa said, we worked intensively with the other labs 370 00:29:43.920 --> 00:29:50.760 on on Nova and Allen, our central station there and a lot 371 00:29:50.760 --> 00:29:55.170 of valuable work was done by Las Animas on over justifying 372 00:29:55.920 --> 00:30:02.280 technical conflict. Mike had this great idea Cody Sian the 373 00:30:04.350 --> 00:30:10.530 nine programs on target shooting in the know their technical 374 00:30:10.530 --> 00:30:15.780 concepts. And these were called the HLP HLP, one to five maybe 375 00:30:15.810 --> 00:30:20.460 already concurrently and ATP wants to five things like show a 376 00:30:20.460 --> 00:30:23.550 convergence of 20 and show you understand the baby tail 377 00:30:23.550 --> 00:30:29.190 instability show you can suppress LPI, etc, etc. And this 378 00:30:29.190 --> 00:30:35.670 codification is very important because that focus the work of 379 00:30:35.670 --> 00:30:41.250 Livermore and Los Alamos and Sandia to some extent on Lobo 380 00:30:41.280 --> 00:30:48.000 justify, and that we understand the target physics program. And 381 00:30:48.030 --> 00:30:53.910 this led to eventually, as I said, the community backing 382 00:30:54.450 --> 00:31:02.970 nests, inputting particular Los Alamos and Sandia. So the when, 383 00:31:03.150 --> 00:31:10.500 when we made the final case for NIST before the 1996, or 1997, 384 00:31:10.950 --> 00:31:16.020 na s committee, they said, they said, Go ahead, they actually 385 00:31:16.020 --> 00:31:16.500 said, 386 00:31:17.850 --> 00:31:21.150 laser micro fusion facility is too big a job. And this is an 387 00:31:21.150 --> 00:31:24.690 intermediate facility showing that we can get ignition, and 388 00:31:24.690 --> 00:31:31.350 this was 1996 1997. And here we are, up the shot last year, 389 00:31:31.350 --> 00:31:37.170 shall we can you mention we were not. We were accurate in our 390 00:31:37.170 --> 00:31:42.660 predictions and review committees worldwide. So my 391 00:31:42.660 --> 00:31:46.260 bottom line is that Nova and Bhima establish the basis and 392 00:31:46.260 --> 00:31:51.240 this was time urgent, we didn't quite recognize it at the time, 393 00:31:51.240 --> 00:31:56.220 because Keith and Jeff Quinn turned and managed to get high 394 00:31:56.220 --> 00:32:00.840 XP conversion from while based on Lee. And had they died a year 395 00:32:00.840 --> 00:32:06.060 too early, and maybe NIF would not have happened. But But Oscar 396 00:32:06.060 --> 00:32:11.040 had witnessed is Mike's great achievement. It's been a 397 00:32:11.040 --> 00:32:14.760 pleasure working on this for many, many years. And it's been 398 00:32:14.760 --> 00:32:18.900 a really great pleasure working with you and for you, Mike, and 399 00:32:19.770 --> 00:32:24.450 I'm greatly honored to be able to say this at you all the time. 400 00:32:24.870 --> 00:32:28.380 Thank you. Thank you, Joe, thank you for Hey. 401 00:32:33.870 --> 00:32:36.870 Let me put it back a little bit to the X ray laser time because 402 00:32:36.870 --> 00:32:41.280 this was a period of really excitement in the program. And I 403 00:32:41.280 --> 00:32:44.370 think really brought a lot of people to the ICF program, 404 00:32:44.370 --> 00:32:46.830 ultimately, not only the technology that's been out of 405 00:32:46.830 --> 00:32:50.640 that, but the people and so let me come back to you, Chris, and 406 00:32:50.670 --> 00:32:52.890 hear what you have to say on that. And then that exciting 407 00:32:52.890 --> 00:32:55.080 time, and maybe Morty will follow up with you. 408 00:32:56.400 --> 00:33:00.270 Yeah, thanks, Dustin. Yeah, I'll go through a couple of specifics 409 00:33:00.270 --> 00:33:02.250 and things that happened in a minute. But I just want to 410 00:33:02.250 --> 00:33:06.240 again, just emphasize that, you know, nowadays, we think of 411 00:33:06.240 --> 00:33:09.360 stockpile stewardship, high energy density physics, you 412 00:33:09.360 --> 00:33:11.760 know, this is all obvious, right? You'd have to have a big 413 00:33:11.760 --> 00:33:15.030 laser as part of a program to maintain nuclear weapons without 414 00:33:15.030 --> 00:33:18.780 testing. This is just obvious. Well, it certainly wasn't 415 00:33:18.780 --> 00:33:22.350 obvious, though, back in the early days, right. And I think 416 00:33:22.350 --> 00:33:24.810 one important thing to mention to remember about the X ray 417 00:33:24.810 --> 00:33:27.750 laser program was it was a case where great science came 418 00:33:27.750 --> 00:33:30.960 together with great technology, both in lasers, and in the 419 00:33:30.960 --> 00:33:33.930 weapons program to solve a problem, which is actually how 420 00:33:33.930 --> 00:33:36.360 things actually work today in the stockpile stewardship 421 00:33:36.360 --> 00:33:40.080 program, so the importance of the entire extra laser effort, 422 00:33:40.590 --> 00:33:44.310 for sure, sort of showing proof of principle for ATT as a tool 423 00:33:44.310 --> 00:33:46.470 for stockpile stewardship, really, it was a critical 424 00:33:46.470 --> 00:33:49.080 contribution, Mike, your leadership and making those 425 00:33:49.080 --> 00:33:52.470 connections obvious People to People was really important at 426 00:33:52.470 --> 00:33:55.620 the conceptual level to Congress, and others. And of 427 00:33:55.620 --> 00:33:59.190 course, it contributed to, you know, NIF as an ignition 428 00:33:59.250 --> 00:34:02.970 facility as well as Joe just very nicely describe it. Just a 429 00:34:02.970 --> 00:34:06.450 little bit of background on the X ray laser period. Again, I got 430 00:34:06.450 --> 00:34:11.430 to Livermore in 1980. And this was a really fun and intense 431 00:34:11.430 --> 00:34:14.760 period for X ray laser research everyone was was competing with 432 00:34:14.760 --> 00:34:19.680 each other watching papers and conferences on a regular basis. 433 00:34:20.310 --> 00:34:23.970 major players again, Livermore the UK rally, as Joe pointed 434 00:34:23.970 --> 00:34:27.090 out, they were a real leader having that facility. My keen 435 00:34:27.090 --> 00:34:31.230 colleagues, Pierre Jacques, les in France, many of you remember 436 00:34:32.010 --> 00:34:37.020 Chris, your work and Pei and Keith, your work at Sandia. Just 437 00:34:37.020 --> 00:34:40.080 lots of excitement. And then you know, basically this all came to 438 00:34:40.080 --> 00:34:44.670 a head in summer 84 When Livermore announced the neon 439 00:34:44.670 --> 00:34:49.590 like Selenium results, which was just a tremendous advance and 440 00:34:49.590 --> 00:34:53.400 just generated huge excitement in the field. And at Princeton. 441 00:34:55.050 --> 00:34:58.170 Our groups led by Shimon cicada also announced some 442 00:34:58.170 --> 00:35:02.670 recombination results as well. So the of APS meeting and 1984. 443 00:35:02.670 --> 00:35:07.590 November 84 was a real watershed for X ray laser research. And it 444 00:35:07.590 --> 00:35:12.300 was it was just a lot of fun. And those are in those days, you 445 00:35:12.300 --> 00:35:14.850 know, to the comments we heard earlier about Peter Hagel, 446 00:35:14.850 --> 00:35:18.180 Steens thesis, there were sort of three schemes will pursue the 447 00:35:18.180 --> 00:35:22.410 collisional excitation, which was what worked in 1984, with 448 00:35:22.410 --> 00:35:26.100 neon like Selenium recombination, which Princeton 449 00:35:26.130 --> 00:35:30.630 was working on also, UK was a primary focus at Rao. And then 450 00:35:30.630 --> 00:35:33.780 resonant photo excitation, which was done at a number of places, 451 00:35:33.780 --> 00:35:37.350 including it with our pulse power facilities. So three great 452 00:35:37.350 --> 00:35:39.480 screams. And then there are, of course, many others over time. 453 00:35:39.840 --> 00:35:44.160 So it's just great to explore all those success in 84. And 454 00:35:44.160 --> 00:35:47.280 then the work continued with a goal of trying to get an extra 455 00:35:47.280 --> 00:35:52.860 laser to the which worked in finally worked in 990 90. I want 456 00:35:52.860 --> 00:35:58.710 to just on the British Invasion point, highlight others in that 457 00:35:58.980 --> 00:36:02.520 play a critical for all x ray laser team. So again, the X ray 458 00:36:02.520 --> 00:36:06.990 laser effort brought together just a great team of 459 00:36:07.290 --> 00:36:10.050 people. Hold on one second, Chris, before we 460 00:36:12.450 --> 00:36:14.340 get to medical there, Chris, just one second. 461 00:36:17.520 --> 00:36:20.910 Now the recording stuff started we're gonna get it out the 462 00:36:20.910 --> 00:36:26.820 window gene test. Six. Let's see if it works. Now. Go ahead. 463 00:36:27.870 --> 00:36:31.560 Okay, great. So anyway, just it was a it was a great period. And 464 00:36:31.560 --> 00:36:34.350 and I just would also, you know, just Mike for you. I would just 465 00:36:34.350 --> 00:36:38.040 also like to mention, one of the reasons this happened is an x 466 00:36:38.040 --> 00:36:41.490 ray laser work continued through 1990 Was your realization of the 467 00:36:41.490 --> 00:36:44.490 importance of following through in this really leading edge 468 00:36:44.490 --> 00:36:47.850 scientific program again, and looking back and say, Well, this 469 00:36:47.850 --> 00:36:51.150 is obvious, you keep on working out lasers, X ray lasers when 470 00:36:51.150 --> 00:36:54.090 she succeeded, you know, at the time, it often wasn't so 471 00:36:54.090 --> 00:36:57.030 obvious, because there was a lot of programmatic pressures and a 472 00:36:57.030 --> 00:37:00.390 lot of pressure to do other things. And so Mike, your 473 00:37:00.390 --> 00:37:03.090 adherence to getting a carrying us through all the way into the 474 00:37:03.090 --> 00:37:09.120 early 90s on this and your dedication to, to getting doing 475 00:37:09.120 --> 00:37:11.340 the best science and making the maximum impact and it's 476 00:37:11.340 --> 00:37:13.980 important field is really appreciate it was very 477 00:37:13.980 --> 00:37:16.710 important. So I'll just finished again, Mike, it's an 478 00:37:16.710 --> 00:37:19.680 extraordinary honor to be here today, and to salute you for all 479 00:37:19.680 --> 00:37:20.700 your work. So thank you. 480 00:37:21.960 --> 00:37:22.740 Thank you, Chris. 481 00:37:23.130 --> 00:37:27.030 Chris. Chris said the follow up question. One of the other 482 00:37:27.030 --> 00:37:29.460 things that always seemed like that was that there truly is a 483 00:37:29.460 --> 00:37:35.100 program really advanced the whole field of diagnostics, on 484 00:37:35.100 --> 00:37:36.150 these facilities. 485 00:37:36.870 --> 00:37:38.310 Could you comment on that? 486 00:37:38.820 --> 00:37:42.600 Yeah, that's absolutely right. Chris, I mean, street cameras, 487 00:37:42.600 --> 00:37:46.680 framing cameras, you know, the ability because as I think Marty 488 00:37:46.980 --> 00:37:50.670 alluded to, what really made it work was not some esoteric 489 00:37:50.670 --> 00:37:53.700 atomic physics issue, but rather, you know, plasma 490 00:37:53.700 --> 00:37:56.490 physics, right, getting the X ray laser to propagate and 491 00:37:56.490 --> 00:38:00.660 diagnostics are critical to to being able to see that. Okay, so 492 00:38:00.660 --> 00:38:03.660 yeah, if it weren't for those advances, we wouldn't have made 493 00:38:03.660 --> 00:38:08.820 it. And diagnostics have actually, in fact, enabled most 494 00:38:08.850 --> 00:38:12.510 many or most of the scientific advances that have happened in 495 00:38:12.510 --> 00:38:17.490 hGD, laser fusion and its relationship. Already, would you 496 00:38:17.490 --> 00:38:18.360 like an opportunity to 497 00:38:18.600 --> 00:38:22.440 talk about X ray lasers a little bit before we pivot over to Los 498 00:38:22.440 --> 00:38:26.910 Alamos and some of Mike's contributions there. 499 00:38:27.810 --> 00:38:33.480 Yeah, I sort of want to focus on one main thing. And it has to do 500 00:38:33.480 --> 00:38:38.460 even with stewardship today. The most important thing of all is 501 00:38:38.460 --> 00:38:45.420 people and the X ray laser efforts brought in such quality 502 00:38:45.420 --> 00:38:49.620 people and Mike Campbell, is the great recruiter, besides the 503 00:38:49.620 --> 00:38:52.590 great communicator and the great connector. He's the great 504 00:38:52.590 --> 00:38:57.330 recruiter. Obviously, Joe Kennedy is the poster child for 505 00:38:57.390 --> 00:39:03.750 a great recruit, because Joe really became the leader. But in 506 00:39:03.750 --> 00:39:08.400 the X ray laser effort itself, that people recruited, just go 507 00:39:08.400 --> 00:39:12.930 through a few names and for x ray laser work, Jim traipse, he 508 00:39:12.930 --> 00:39:17.280 became the head of the physics department, Brian McGowan, and 509 00:39:17.280 --> 00:39:20.640 Bruce Hamel. They each in their turn were head of the ICF 510 00:39:20.640 --> 00:39:27.660 program. Chris Kane, of course, we've heard from and on the 511 00:39:27.660 --> 00:39:32.040 theory side, rich London is distinguished physicist. And so 512 00:39:32.040 --> 00:39:35.250 the extra laser program in my view, one of its great 513 00:39:35.490 --> 00:39:39.480 contributions in the end, besides maybe winning the Cold 514 00:39:39.480 --> 00:39:45.930 War was was the people that became leaders. And that's a 515 00:39:45.930 --> 00:39:50.340 very important concept that I wanted to get across. I'll just 516 00:39:50.340 --> 00:39:51.180 leave it at that. 517 00:39:53.010 --> 00:39:56.100 Thanks, Mark. We're gonna pivot a little bit we can always come 518 00:39:56.100 --> 00:40:00.450 back to that but Melissa, do you know how was how was My viewed 519 00:40:00.450 --> 00:40:04.110 in Los Alamos over this time, and what do you what are your 520 00:40:04.140 --> 00:40:15.690 What are your thoughts on that it has in the 1980s? TSC? I 521 00:40:15.690 --> 00:40:17.100 think you're muted if you're talking 522 00:40:18.390 --> 00:40:20.160 to think better. There we go. 523 00:40:24.900 --> 00:40:28.080 Yellow Light. Everybody. We don't 524 00:40:28.890 --> 00:40:30.330 we still don't hear you, Melissa. 525 00:40:32.100 --> 00:40:38.550 Can you hear me now? Yeah. In the early era, in the late 80s, 526 00:40:38.550 --> 00:40:43.950 Mike was seen by most people at Los Alamos as a great threat. 527 00:40:44.520 --> 00:40:49.200 But a great salesman, and people were speculating on what was 528 00:40:49.200 --> 00:40:53.490 being sold next. Some of us who are coming up through the 529 00:40:53.490 --> 00:40:58.350 trenches, at that time in the 80s, really, were looking around 530 00:40:58.350 --> 00:41:02.730 the country for a leadership and an ICF. And we were struggling 531 00:41:02.760 --> 00:41:07.170 to see it. And then, as we started looking for 532 00:41:07.170 --> 00:41:13.230 collaborations in the NOVA program with Joe and Morty, and 533 00:41:14.310 --> 00:41:18.600 folks at Livermore, it was obvious that the great leader in 534 00:41:18.600 --> 00:41:24.960 the program was Mike. And we at Los Alamos had to lock the line 535 00:41:25.650 --> 00:41:30.450 of how we stay true to our beliefs. And what we thought was 536 00:41:30.720 --> 00:41:34.020 the credibility of the experimental work going on it 537 00:41:34.020 --> 00:41:39.630 No, but and also to try to be able to come and contribute to 538 00:41:39.630 --> 00:41:43.800 the Nova technical program as well. And that was very hard 539 00:41:43.800 --> 00:41:47.340 coming from a Los Alamos perspective. And it took the 540 00:41:47.340 --> 00:41:52.770 leadership of Mike, and people like Joe, to recognize that, 541 00:41:53.910 --> 00:41:59.190 that there were some very forward leaning ideas at Los 542 00:41:59.190 --> 00:42:03.570 Alamos that could be applied to the Nova technical contract, and 543 00:42:03.600 --> 00:42:07.560 that could move the program forward. And I must say, having 544 00:42:07.560 --> 00:42:12.270 been in later leadership positions, and as deputy of the 545 00:42:12.270 --> 00:42:16.170 weapons program at Livermore, that's one of the hard things to 546 00:42:17.130 --> 00:42:21.570 to accomplish is how you leave your program at your laboratory, 547 00:42:21.900 --> 00:42:26.130 but find find room for exceptional contributions from 548 00:42:26.130 --> 00:42:31.680 others. And I think Mike always knew that and that was something 549 00:42:31.710 --> 00:42:35.250 innate to his nature that you could see play out through his 550 00:42:35.250 --> 00:42:40.800 whole career. Things that Los Alamos worked on for Livermore 551 00:42:40.800 --> 00:42:44.460 ahead the history of the weapons program and lasers. It wasn't 552 00:42:44.460 --> 00:42:48.090 there at Los Alamos, it just wasn't. And the weapons program 553 00:42:48.090 --> 00:42:52.260 was extremely skeptical of any utility of hydrogen density 554 00:42:52.260 --> 00:42:57.000 physics for a very long time. But through Mike's leadership, 555 00:42:57.180 --> 00:43:00.900 Los Alamos was able to execute some the first weapons physics 556 00:43:00.900 --> 00:43:04.710 experiment, a few of us from the underground test program, worked 557 00:43:04.710 --> 00:43:09.180 on the design and executed the experiments on Nova. It was 558 00:43:09.180 --> 00:43:13.110 highly successful. And that heralded in a new era for Los 559 00:43:13.110 --> 00:43:16.800 Alamos. So largely that was because Mike helped make that 560 00:43:16.800 --> 00:43:22.440 happen. There were was the work by Ellen Hauer and others at Los 561 00:43:22.440 --> 00:43:29.520 Alamos, working on symmetry on ANOVA. Those experiments went 562 00:43:29.520 --> 00:43:32.970 pretty well. But there are other experiments in plasma physics, 563 00:43:33.270 --> 00:43:37.350 where we came to blows with Livermore. And I remember many, 564 00:43:37.350 --> 00:43:41.220 many late night conversations, almost all my conversations with 565 00:43:41.220 --> 00:43:45.450 Mike as I became leader of the ICF program at Los Alamos, or 566 00:43:45.450 --> 00:43:48.480 after eight o'clock at night, you know, I would get the call, 567 00:43:48.540 --> 00:43:51.450 I knew it wasn't, you know, the boyfriend I wasn't paying 568 00:43:51.450 --> 00:43:54.510 attention to because I was working all the time. I knew it 569 00:43:54.510 --> 00:43:59.280 was my calling, and wanting to chat about like, what new 570 00:43:59.520 --> 00:44:04.050 problems the plasma physicists at Los Alamos were causing for 571 00:44:04.290 --> 00:44:11.700 politics on this. I mean, it was highly collaborative at all 572 00:44:11.700 --> 00:44:17.580 times. But it took a while for the the leadership at Los Alamos 573 00:44:17.580 --> 00:44:23.040 to understand where Mike was trying to go, and I think they 574 00:44:23.040 --> 00:44:26.730 didn't always believe it. They didn't always believe everything 575 00:44:26.730 --> 00:44:29.940 he was saying. They didn't necessarily believe the vision, 576 00:44:29.970 --> 00:44:34.710 but many of us working at lower levels, we did believe it and we 577 00:44:34.710 --> 00:44:41.550 tried to go where his vision led us toward nips. I can only say 578 00:44:41.550 --> 00:44:44.910 from my perspective, I always thought Mike is an incredible 579 00:44:44.910 --> 00:44:50.520 leader and incredible salesman. Always working people and 580 00:44:50.520 --> 00:44:54.480 working the system, but also doing it with with the reality 581 00:44:54.510 --> 00:44:59.250 that he truly cared about the individual and truly cared about 582 00:44:59.250 --> 00:44:59.940 the science 583 00:45:02.460 --> 00:45:03.450 Yeah, well said, 584 00:45:03.480 --> 00:45:04.380 Melissa, well said, 585 00:45:04.620 --> 00:45:05.430 Thank you, Melissa. 586 00:45:07.560 --> 00:45:10.650 Let me put it back to you, Joe. And one of the questions about 587 00:45:10.890 --> 00:45:14.670 how the laboratory micro fusion facility evolved into the 588 00:45:14.670 --> 00:45:19.590 National Ignition Facility and maybe any stories and that you 589 00:45:19.590 --> 00:45:22.830 can remember and Mike's role in selling that program, I think 590 00:45:23.070 --> 00:45:26.640 all of us recognize a critical component to that. 591 00:45:27.930 --> 00:45:39.600 Yeah. I have a meeting, which is the same time as the so called 592 00:45:39.780 --> 00:45:47.100 Madrid manifesto, the manifesto. I don't know why we get that 593 00:45:47.100 --> 00:45:53.400 most, but can you still hear me? Can you still 594 00:45:55.020 --> 00:45:59.640 get an echo Joe? Okay. 595 00:46:04.020 --> 00:46:05.130 Joe, why don't you? 596 00:46:07.710 --> 00:46:10.230 Why don't you turn your video off just in case and it says 597 00:46:10.230 --> 00:46:11.310 it's suggesting the bandwidth. 598 00:46:12.840 --> 00:46:17.520 And we were very optimistic in our costing of it. 599 00:46:19.200 --> 00:46:27.000 embarrassingly low number that I conveniently forget. But as we 600 00:46:27.000 --> 00:46:32.760 develop the laser technology for Mike was there a lot more about 601 00:46:32.760 --> 00:46:40.500 this? And was a breakthrough probably credited to John as in 602 00:46:40.500 --> 00:46:45.270 limbo of going to higher temperatures. We thought in the 603 00:46:45.270 --> 00:46:52.650 end that we could get there with I think we said 1.3 mega joules 604 00:46:54.900 --> 00:47:03.150 out of 10 or 20% and thus the NIF was designed to be a 1.8 605 00:47:03.150 --> 00:47:11.880 mega joule facility and that all happen in the end of the 80s and 606 00:47:12.330 --> 00:47:18.900 then beginning of the 90s but it was the laser technology in 607 00:47:18.900 --> 00:47:30.060 particular I think that enabled us to cost cost the net more 608 00:47:30.060 --> 00:47:34.140 accurately I trying to figure out how to do this create screen 609 00:47:34.140 --> 00:47:34.740 sharing 610 00:47:39.870 --> 00:47:42.630 if it's easier Joe you can email it to me as well I can 611 00:47:42.630 --> 00:47:51.360 showcase I've been unsuccessful in doing okay. So so then the 612 00:47:51.360 --> 00:47:59.820 other thing I would mention for the my memory here was the what 613 00:47:59.820 --> 00:48:10.800 is the Cinderella guess what the Cinderella was and guess who was 614 00:48:11.940 --> 00:48:15.900 a major league leader at Los Alamos for target fabrication, 615 00:48:15.930 --> 00:48:25.380 it was Lowry foreman. One of the other miracles of icy is beta 616 00:48:25.380 --> 00:48:29.250 layering. Beta layering as you all must have you must know is a 617 00:48:29.250 --> 00:48:34.650 process where a slightly thicker piece of cryogenic deuterium 618 00:48:35.130 --> 00:48:41.280 sublimates and becomes thinner and smoothed out because of the 619 00:48:41.280 --> 00:48:45.990 basic decay of the tritium and and that that again was I think 620 00:48:45.990 --> 00:48:51.840 that was invented at Los Alamos wasn't it but it's a bind nobody 621 00:48:51.840 --> 00:48:57.270 you know battle or someone like that. But Lowry as informants 622 00:48:58.200 --> 00:49:06.480 who unfortunately died a while ago. Mike, I believe I believe 623 00:49:06.480 --> 00:49:11.340 this divine like you managed to get him the Talent Award before 624 00:49:11.340 --> 00:49:28.320 he died. Oh, Mike. B. Let me again say that it's very fitting 625 00:49:28.650 --> 00:49:36.450 that you've retired now. I can can my screen be seen? 626 00:49:39.630 --> 00:49:42.780 Yeah, I'm still not still not doing it. If you send it to me. 627 00:49:43.020 --> 00:49:46.140 I can put it up, Joe. It's easy for you. 628 00:49:46.710 --> 00:49:54.660 Anyway, so Melissa, I believe I made up a baseball cap that says 629 00:49:55.050 --> 00:49:58.470 in Latin, I don't think she was a great Latin scholar actually. 630 00:49:58.470 --> 00:50:03.090 Nor was I but it It says in Latin ignitions before 631 00:50:03.090 --> 00:50:08.220 retirement. So isn't that prescient? Yeah, we got ignition 632 00:50:08.220 --> 00:50:12.540 last year. Well, most, and now you've retired. So 633 00:50:12.540 --> 00:50:17.160 congratulations, Mike ignition. And before retirement, you did 634 00:50:17.160 --> 00:50:17.640 it make. 635 00:50:19.470 --> 00:50:22.440 I was supposed to bring a hat for you. And I think I have it 636 00:50:22.440 --> 00:50:30.300 but I couldn't find we had 637 00:50:32.790 --> 00:50:35.520 let's just say something so pops up onto the center of the 638 00:50:35.520 --> 00:50:41.550 screen, if you can do it, 639 00:50:41.820 --> 00:50:43.020 or you can make it fullscreen. 640 00:50:46.890 --> 00:50:52.110 It's a huge pleasure to say that Mike actually made it. After 641 00:50:52.110 --> 00:50:56.700 retirement, you know, many of us we bailed out before retirement. 642 00:50:56.700 --> 00:50:57.150 So. 643 00:51:01.470 --> 00:51:07.950 Great. So big, up to the panel. Is there anything we've missed 644 00:51:07.950 --> 00:51:11.430 that you'd like to share? Anyone have anything they want to 645 00:51:11.580 --> 00:51:18.120 summarize? Before we move on? If you didn't, I will absolutely 646 00:51:18.120 --> 00:51:24.630 come to you in a second. Anything there? Okay. So you 647 00:51:24.630 --> 00:51:28.440 know, I think it's pretty neat the revolution of the 1980s and 648 00:51:28.440 --> 00:51:31.590 love both, you know, lasers, laser science. And of course, 649 00:51:31.590 --> 00:51:35.610 the bridge was really foundation for much of what LLP is today. 650 00:51:35.940 --> 00:51:39.750 Right? If you think about that, and it fostered that transition 651 00:51:39.750 --> 00:51:43.440 from IFP focus laboratory to one that supports the science 652 00:51:43.440 --> 00:51:49.650 stockpile stewardship. In a way, we have a lot to thank you for 653 00:51:49.650 --> 00:51:52.770 In addition, as you listen to these stories, and you recognize 654 00:51:52.770 --> 00:51:57.420 the connections and you see what we are have become and how 655 00:51:57.420 --> 00:52:01.650 fitting it was for you to end your career at the laboratory as 656 00:52:01.650 --> 00:52:05.580 our director by remarkable, so let me open it up to you, Mike 657 00:52:05.580 --> 00:52:09.510 and give you a chance to share about the 1988 and 658 00:52:10.050 --> 00:52:11.280 the the stories. 659 00:52:12.060 --> 00:52:15.960 It was a wonderful time, as Joe said, and Morty said, somebody's 660 00:52:15.960 --> 00:52:19.440 got a little bit x ray lasers first. So actually, when I went 661 00:52:19.440 --> 00:52:21.690 live while I was very interested in X ray laser, because I just 662 00:52:21.690 --> 00:52:24.690 work I did the principles on recombination lasers actually 663 00:52:24.690 --> 00:52:28.890 made I actually made a recombination visible laser. But 664 00:52:28.920 --> 00:52:32.970 when we started doing as Marty and I said before, there was a 665 00:52:33.000 --> 00:52:36.690 no connection between a weapons program and lasers, and more I 666 00:52:36.690 --> 00:52:40.080 remember Morty doing a lot of work with AIDS, okay of saying 667 00:52:40.110 --> 00:52:42.840 he could do relevant work in the laser in the laboratory for the 668 00:52:42.840 --> 00:52:44.430 weapons permit. They just weren't interested because they 669 00:52:44.430 --> 00:52:47.700 were testing and then like, but the X ray laser program came 670 00:52:47.700 --> 00:52:52.800 along. And the lab wanted Peter Hagelstein to get known for his 671 00:52:52.800 --> 00:52:55.260 work, because they were fearful that he would leave the 672 00:52:55.260 --> 00:53:00.060 laboratory. And so I was instructed to, you know, open up 673 00:53:00.060 --> 00:53:03.060 to that. And so that's when Morty got involved. I remember 674 00:53:03.090 --> 00:53:05.820 coming, I'll become we're only at seven o'clock morning and I 675 00:53:05.820 --> 00:53:08.790 think I'd have to wake up and Morty was on his on his sleeping 676 00:53:08.790 --> 00:53:12.240 bag in his office. I remember that many times. Having to you 677 00:53:12.240 --> 00:53:14.550 know, he was just waking up. I thought so I gave him coffee, 678 00:53:14.550 --> 00:53:18.180 whatever it was, but I remember that. And then what how this 679 00:53:18.180 --> 00:53:21.840 came about, you know, the the target design, we were pogroms 680 00:53:21.840 --> 00:53:25.230 reclassified. At that time, we knew that ramen was the major 681 00:53:25.230 --> 00:53:28.350 hot electron source, but we couldn't talk about it. So I 682 00:53:28.350 --> 00:53:32.580 asked Paul Drake recruiting from The MFE program to come in let's 683 00:53:32.580 --> 00:53:35.040 design experiments that could show Raman could be very 684 00:53:35.040 --> 00:53:38.010 efficient. And so the exploding coils were developed for that. 685 00:53:38.430 --> 00:53:43.950 And then I remember we were shooting selenium. This nothing 686 00:53:43.980 --> 00:53:46.770 saying nothing. So Peter Hagelstein pains my office one 687 00:53:46.770 --> 00:53:50.910 day and literally was crying, this is not going to work. It's 688 00:53:50.910 --> 00:53:54.960 not going to work. And we started talking, I started go, 689 00:53:55.020 --> 00:53:57.960 Well, you don't We don't need so these things have gained five 690 00:53:57.960 --> 00:54:00.180 inverse centimeters. So we don't measure gain, we measure 691 00:54:00.180 --> 00:54:04.170 amplification and has to propagate. And, and there's 692 00:54:04.170 --> 00:54:06.630 conditions that the plasma density and temperature were 693 00:54:06.630 --> 00:54:09.510 like what we're seeing for the ROM and stuff. And so I looked 694 00:54:09.510 --> 00:54:12.450 at that, well, this is a convective instability to we 695 00:54:12.450 --> 00:54:15.450 need shallow gradients. And so I went the morning, that's all 696 00:54:15.450 --> 00:54:17.700 morning, I had that discussion, and then morning did design 697 00:54:17.700 --> 00:54:22.500 work, and showed it worked. And then I remember the first shot I 698 00:54:22.500 --> 00:54:26.790 was home. Dennis Matt was doing the experiments. He said, You 699 00:54:26.790 --> 00:54:28.740 got to come into the lab, there's like midnight, so I 700 00:54:28.740 --> 00:54:31.710 drove into the lab. One of the we're still recording it on 701 00:54:31.710 --> 00:54:37.620 film, kind of caught my eye was a great guy pulled out the film 702 00:54:37.620 --> 00:54:41.280 and there were two black spots. Basically burn holes in the film 703 00:54:41.280 --> 00:54:44.850 work the first time, Denison went down to a little bar and I 704 00:54:44.850 --> 00:54:50.310 had a Diet Coke and didn't have Cosmo's at the time. But that 705 00:54:50.310 --> 00:54:52.980 was that was the beginning of the weapons program showing at 706 00:54:52.980 --> 00:54:56.490 least beginning some interest in this. And so it was more he said 707 00:54:56.490 --> 00:55:00.600 it was the beginning of weapons. Beginning of It took a longer 708 00:55:00.600 --> 00:55:04.380 time, you know, to do this, some of the other things. And but one 709 00:55:04.380 --> 00:55:07.650 of the things about diagnostics, as you all know, UV lithography. 710 00:55:08.190 --> 00:55:12.450 He is the lithography came out of the X ray laser program. And 711 00:55:12.450 --> 00:55:17.100 there was a guy, Andy heroic. His brother was a famous 712 00:55:17.100 --> 00:55:20.760 physicist at Princeton. He came to me one day and said, We can 713 00:55:20.760 --> 00:55:24.420 do lithography. Now, we can do lithography. And I said, you 714 00:55:24.420 --> 00:55:28.140 know, what are you talking about? So I first learned about 715 00:55:28.140 --> 00:55:31.740 the photography and member feature size depend on the 716 00:55:31.740 --> 00:55:34.440 wavelength of the light. And at that time, the wavelength was in 717 00:55:34.440 --> 00:55:38.100 the UV and we were making 100 100 angstrom light. So it 718 00:55:38.100 --> 00:55:41.340 says, Well, we have the mirrors that actually can now focus in 719 00:55:41.340 --> 00:55:44.280 you know, and do all the things you do with photography. So he 720 00:55:44.280 --> 00:55:48.090 said, there's a conference in Florida, can I go to it? You 721 00:55:48.090 --> 00:55:50.520 know, I didn't ask Dave Crandall if he was okay. So I said, Sure. 722 00:55:50.520 --> 00:55:53.490 And I said, but the last few graphs you make anyone 723 00:55:53.490 --> 00:55:57.900 interested, please call Mike Campbell. So Andy goes and gives 724 00:55:57.900 --> 00:56:02.280 a talk says it went great. A week later, Bill Brinkman, Bob 725 00:56:02.280 --> 00:56:05.610 dine of dimes, and recruitment, called me up said this looks 726 00:56:05.610 --> 00:56:08.550 pretty interesting. And so that was being a deal, easy 727 00:56:08.550 --> 00:56:13.950 lithography. So and now, a billion transistors in this, he 728 00:56:13.950 --> 00:56:17.310 is the lithography. So the ISIS of the laser fusion program 729 00:56:17.340 --> 00:56:20.280 invented the UV lithography. And as I was like, remind people 730 00:56:20.280 --> 00:56:23.460 that it was not just a diagnostic, it was actually a 731 00:56:23.460 --> 00:56:28.470 spin off technology. Now that Joe talked about Nova, so we 732 00:56:28.470 --> 00:56:32.880 were at that time, Nova was run by a different organization than 733 00:56:32.880 --> 00:56:35.610 the experiments program. And we're having lots of problems 734 00:56:35.610 --> 00:56:40.200 with Nova. And so I went to John Emmett and said, Well, why don't 735 00:56:40.380 --> 00:56:43.230 the experimentalist take over? No, because we want to get data. 736 00:56:44.010 --> 00:56:48.330 And after a bunch of arguments, you said yes. And then I put Joe 737 00:56:48.330 --> 00:56:54.840 Kilkenny in charge. And I got a call from the engineers. They 738 00:56:54.870 --> 00:56:58.350 took me into the conference room and 381 Close the door, and I 739 00:56:58.350 --> 00:56:59.490 thought they were going to kill me. 740 00:57:00.870 --> 00:57:05.490 No, it was not we Oh, Joe just wants bubble tape and bubble gum 741 00:57:05.490 --> 00:57:09.570 that challenge want to make things work. And of course, the 742 00:57:09.570 --> 00:57:12.780 rest is history. Joe did a great job, Nova, we did precision 743 00:57:12.780 --> 00:57:16.260 Nova, the first power balance, the first pulse shaping was done 744 00:57:16.260 --> 00:57:20.340 on Nova and all the diagnostics and the technical contract and 745 00:57:20.340 --> 00:57:25.020 the ANOVA. One from 200 shots a year, a shot a day used to keep 746 00:57:25.020 --> 00:57:26.940 that this is why that was the end of that was what people 747 00:57:26.940 --> 00:57:33.390 didn't say 1400 with axes with no increased costs, because Jo 748 00:57:33.420 --> 00:57:36.360 Jo worked with the technicians and the engineers to make the 749 00:57:36.360 --> 00:57:41.040 machine much more user friendly, and actually much more 750 00:57:41.100 --> 00:57:44.010 efficient. So just so Jojo, there's a lot of credit for 751 00:57:44.010 --> 00:57:47.520 that. And it was a again, I still remember the engineers, 752 00:57:47.820 --> 00:57:50.850 they literally were screaming at me, you can't do that you can't 753 00:57:50.850 --> 00:57:52.770 do this and but at work, 754 00:57:53.550 --> 00:57:55.770 may have pulled the trigger on that. Because, you know, when 755 00:57:55.770 --> 00:57:59.580 Nova was then shut down, you know, was quite a distance 756 00:57:59.580 --> 00:58:03.090 before test net was good come up, you know, so how hard a 757 00:58:03.090 --> 00:58:04.380 decision was that to make? 758 00:58:05.460 --> 00:58:09.840 So what had happened actually, it goes back to Nova. Because 759 00:58:09.840 --> 00:58:13.230 what happened was, we had no vet that's where the first X ray 760 00:58:13.230 --> 00:58:17.670 laser was done. And everyone's attention to terminal program 761 00:58:17.670 --> 00:58:21.570 was focused on doing it's doing work on no bet. So Nova Nova was 762 00:58:21.630 --> 00:58:25.230 came on mine, it didn't work. And so we made up this word 763 00:58:25.230 --> 00:58:30.150 precision Nova basically to fix Nova. And it made an enormous 764 00:58:30.150 --> 00:58:33.450 impression me that you have to get, you will if you have an 765 00:58:33.450 --> 00:58:35.970 operating facility, people will not pay attention to the one 766 00:58:35.970 --> 00:58:40.050 being built. And so I made a decision to shut down Nova. 767 00:58:40.500 --> 00:58:43.110 People weren't happy with it. For two reasons that was 768 00:58:43.110 --> 00:58:46.530 wondering the other reason was, Omega was more NIF like the Nova 769 00:58:46.530 --> 00:58:50.880 was no it had, we could put 40 beams into a whole room. We're 770 00:58:50.880 --> 00:58:53.880 no look, I only put 10 beams in the house was more or less like 771 00:58:53.880 --> 00:58:58.500 and so that was the reason. So Bob, the I talked to Bob. And 772 00:58:58.530 --> 00:59:03.600 Bob willingly did this and gave I think a lot of work on getting 773 00:59:03.600 --> 00:59:06.450 NIF eventually to work. The physics was done here. The 774 00:59:06.450 --> 00:59:08.880 diagnostics were I mean, there were people Jim can our oils are 775 00:59:08.880 --> 00:59:13.020 out in the field spend time at the Livermore Sean did. So So 776 00:59:13.560 --> 00:59:18.120 there's those two reasons. And so lesson learned for any 777 00:59:18.120 --> 00:59:20.880 facility to be built is to make sure that the people who are 778 00:59:20.880 --> 00:59:24.330 going to use it are involved in the design construction and 779 00:59:24.360 --> 00:59:27.990 learning how operated. So that was a reason. And we the other 780 00:59:27.990 --> 00:59:30.270 thing that happened on Nova I guess we'll talk about it. The 781 00:59:30.270 --> 00:59:32.850 next thing about petawatt that was also an interesting thing, 782 00:59:32.850 --> 00:59:37.560 which is also very much involved LOA sounds good. We 783 00:59:37.560 --> 00:59:40.260 have anything from the audience that one before we wrap up this 784 00:59:40.260 --> 00:59:40.860 session. 785 00:59:42.360 --> 00:59:43.650 Jim can our so 786 00:59:45.180 --> 00:59:53.400 go back to the servers here. This is when I first met. At the 787 00:59:53.400 --> 01:00:01.590 time, I was working for Lockheed primarily and I'm going to chase 788 01:00:01.650 --> 01:00:02.610 my boss at the time 789 01:00:06.720 --> 01:00:10.500 to talk about results that they got back from underground tests. 790 01:00:13.710 --> 01:00:18.480 And he came back to Palo Alto, called me into his office. And 791 01:00:18.480 --> 01:00:22.710 he said, The problem with whether their diagnostics, this 792 01:00:22.710 --> 01:00:31.950 was a multi anode, X ray, multi cabinet. And he says, I asked 793 01:00:31.950 --> 01:00:36.600 you, me to calibrate at our coast X ray facility that we had 794 01:00:36.990 --> 01:00:41.250 last year, this was my first interaction with Mike, and also 795 01:00:41.250 --> 01:00:49.620 my first interaction with with people like MARC record. And so 796 01:00:49.650 --> 01:00:54.810 I thank you for that. That was a real eye opener. And that was, 797 01:00:55.320 --> 01:01:00.330 this is like outside of national laboratory environment more with 798 01:01:00.330 --> 01:01:00.840 the pregnancy. 799 01:01:02.790 --> 01:01:05.520 I remember that your mother's. And you're right, there were 800 01:01:05.520 --> 01:01:07.290 some real diagnostic problems. 801 01:01:07.710 --> 01:01:12.750 Yeah, we have to what we ended up finding out was that the ADC 802 01:01:12.750 --> 01:01:16.650 back in the beam was nowhere near a colony that they thought 803 01:01:16.650 --> 01:01:20.190 it was, Well, turns out there was a detector issue, not an x 804 01:01:20.190 --> 01:01:26.010 ray laser, because with these multi cathode X ray dial, they 805 01:01:26.010 --> 01:01:28.830 were capacitively coupled to the other Catholics. 806 01:01:32.040 --> 01:01:32.910 I see some other gems. 807 01:01:33.720 --> 01:01:37.140 Yeah. You all attention to that, because a lot of times on about 808 01:01:37.140 --> 01:01:40.950 X ray, the X ray X ray laser recent faculty seem to have 809 01:01:40.950 --> 01:01:46.770 fallen out of over the years. So what circumstances do you think 810 01:01:46.770 --> 01:01:48.990 would be needed for the 811 01:01:53.250 --> 01:01:58.110 so I will say we, I easily looked into X ray lasers for 812 01:01:58.110 --> 01:02:01.380 flying focus a few years ago and contacted Livermore and had some 813 01:02:01.380 --> 01:02:07.650 interaction. It's a thriving, amazing field that has gone 814 01:02:07.740 --> 01:02:12.750 essentially have oscillators in general, much like a laser that 815 01:02:12.750 --> 01:02:17.130 we're aware of, at a different scale than what was being done 816 01:02:17.130 --> 01:02:21.900 back then. I was shocked at how sophisticated was and it 817 01:02:21.960 --> 01:02:25.650 immediately chased us from the field realizing the bar to get 818 01:02:25.650 --> 01:02:29.280 to that level. And what we wanted to do was was was far 819 01:02:29.280 --> 01:02:32.910 exceeding that, but but I you know, it's still around. I don't 820 01:02:32.910 --> 01:02:38.520 know if someone wants to talk to that more specifically. Welcome. 821 01:02:40.890 --> 01:02:41.550 mentioning him 822 01:02:45.510 --> 01:02:49.200 several elements that describe the acre labor program, the 823 01:02:49.200 --> 01:02:55.860 competing, right, yeah, three major phases. The UK and Spanish 824 01:02:55.860 --> 01:03:02.100 team. I don't know, you know, besides competing with the likes 825 01:03:02.100 --> 01:03:08.160 of collaboration is happening at the same time. That Atos is 826 01:03:08.160 --> 01:03:13.440 motivated when the lava was shut down. A lot of the components 827 01:03:13.470 --> 01:03:20.460 were distributed to the influential community. And I 828 01:03:20.460 --> 01:03:23.550 actually benefit from that kind of innovation, right? That's 829 01:03:23.550 --> 01:03:27.030 kind of the follow up discussion on the pedal our laser high 830 01:03:27.030 --> 01:03:31.590 intensity lasers, you know, the world. My team took a little bit 831 01:03:31.620 --> 01:03:35.310 about that competing, but also collaboration. 832 01:03:36.210 --> 01:03:42.150 So when Nova shut down, I wanted to send basically who would who 833 01:03:42.150 --> 01:03:45.660 want to know the price. You know, they could be able to just 834 01:03:45.660 --> 01:03:48.240 creatively just have to later just go into a warehouse or be 835 01:03:48.240 --> 01:03:52.890 destroyed. So work with DOE and south so they could be sent to 836 01:03:52.890 --> 01:03:58.440 Germany, other places. And then when Vemma was done, we made the 837 01:03:58.440 --> 01:04:02.670 deal to send it to San Diego. Cassandra's argument that was if 838 01:04:02.670 --> 01:04:07.800 you looked at and this was Joe's working on okay? What's 839 01:04:07.800 --> 01:04:11.070 backlighting? Nova did a lot of radiography with the 10 beams, 840 01:04:11.070 --> 01:04:13.500 we have to be able to to make what to do it react and Sandy 841 01:04:13.500 --> 01:04:17.010 had nothing, they had no radiographic source. So Howard 842 01:04:17.010 --> 01:04:21.360 Powell and Joe and I talked about it and sent it down to 843 01:04:22.590 --> 01:04:25.710 Sandia. And so it's been a major tool for them, you know, in lots 844 01:04:25.710 --> 01:04:29.580 of different ways. But the thing about the X ray laser, what 845 01:04:29.580 --> 01:04:34.110 happened? I think, as you know, first Star Wars went away. And 846 01:04:34.110 --> 01:04:38.520 so the interest of the weapons program and that dissipated 847 01:04:39.570 --> 01:04:44.070 exhales came along and that really changed on suddenly we 848 01:04:44.070 --> 01:04:48.510 had an extra laser it was very expensive, of course, but you 849 01:04:48.510 --> 01:04:51.330 know, that that that sort of diminished the role of that with 850 01:04:51.330 --> 01:04:55.380 lasers. But the I still think that they are very interesting 851 01:04:55.380 --> 01:04:58.380 probes. You know, I would like to see more X ray lasers being 852 01:04:58.380 --> 01:05:01.980 used in our in our probe. Am I actually we did on the on Nova 853 01:05:01.980 --> 01:05:05.100 we did interferometry with X ray lasers, we actually use it as a 854 01:05:05.100 --> 01:05:07.980 diagnostic tool. I would like to I think that needs to be 855 01:05:07.980 --> 01:05:11.220 relooked at because it can probe higher density plasmas. I mean, 856 01:05:11.220 --> 01:05:14.580 Dustin is on wonderful Thompson scattering and such holism. And 857 01:05:14.850 --> 01:05:17.160 how far you can from the probe is limited by the wavelength of 858 01:05:17.160 --> 01:05:18.930 light, you're doing the gradients and things like that. 859 01:05:18.930 --> 01:05:22.140 So I think it'd be something that is, as we look forward to 860 01:05:22.170 --> 01:05:24.840 it was Chris annual report is that there's an opportunity, I 861 01:05:24.840 --> 01:05:28.410 think, to read look at that for as a as a diagnostic probe. 862 01:05:28.980 --> 01:05:32.610 The X ray lasers may come back in the next session as well, in 863 01:05:32.610 --> 01:05:35.850 that, you know, I think part of what also flowed that program 864 01:05:35.850 --> 01:05:40.530 down was the science stockpile stewardship program, as the end 865 01:05:40.530 --> 01:05:43.530 of underground testing, because that was clearly some of the big 866 01:05:43.530 --> 01:05:44.940 tests that were going on at the end. 867 01:05:45.300 --> 01:05:47.760 I want to point out something from the government side, Mike 868 01:05:47.760 --> 01:05:53.820 can come in and I hope in 1990, Jim Watkins had a fusion Policy 869 01:05:53.820 --> 01:05:57.180 Advisory Committee is where I met Bob sprawl and Arthur 870 01:05:57.180 --> 01:06:02.190 Kerman, for example. And, frankly, that we're still 871 01:06:02.190 --> 01:06:08.160 operating under that, that policy. And it had a great 872 01:06:08.160 --> 01:06:11.580 influence. It was, it was that same time that the National 873 01:06:11.580 --> 01:06:15.750 Academy was looking at LM F and suggesting each did something 874 01:06:15.750 --> 01:06:24.600 like Neff. And we fried Eric storm and Bama curry said we 875 01:06:25.800 --> 01:06:29.040 something to the effect, we can't ignite we can 876 01:06:33.060 --> 01:06:34.260 read but put 877 01:06:34.260 --> 01:06:42.210 $2,000 and $2 billion will lead something. Do you have any 878 01:06:42.210 --> 01:06:45.060 recollections about fusion Policy Advisory Committee and 879 01:06:45.060 --> 01:06:48.150 how how it affected things? Yeah, well, 880 01:06:48.150 --> 01:06:51.420 it was actually it was a very useful because it was you know, 881 01:06:51.420 --> 01:06:56.700 it's sort of met fairly regularly. Right? Yeah. And, and 882 01:06:56.700 --> 01:06:58.920 it's a really good feel to have people like Marshall Rosenbluth 883 01:06:58.920 --> 01:06:59.820 on it, Marshall made 884 01:06:59.820 --> 01:07:03.540 a great cartoon, you made a great cartoon of Marshall. And 885 01:07:03.570 --> 01:07:04.680 the things he said, 886 01:07:06.540 --> 01:07:10.290 Steve Koonin not at Marshall, do lots of good people. And so it 887 01:07:10.290 --> 01:07:12.840 made the program more transparent. And actually, the 888 01:07:12.840 --> 01:07:14.970 reason why we wrote the technical contract, we had a 889 01:07:14.970 --> 01:07:17.430 meeting in Los Alamos with the National Academy of Sciences, 890 01:07:18.000 --> 01:07:21.960 and they meet irregularly for things, they wouldn't understand 891 01:07:21.960 --> 01:07:28.140 anything on ICF. And then most of the talks were rehashing was 892 01:07:28.170 --> 01:07:31.590 reminding them what they heard before. And there was a way of 893 01:07:31.590 --> 01:07:35.340 judging progress. And so I remember Joe and I are Los 894 01:07:35.340 --> 01:07:38.160 Alamos walk by so we have to write the textbook and we have 895 01:07:38.160 --> 01:07:41.040 to write a program plan that everyone agrees to that they can 896 01:07:41.040 --> 01:07:44.160 see the progress in the field. And so that's that was the 897 01:07:44.160 --> 01:07:47.010 motivation. And then what happened is, I wrote with lots 898 01:07:47.010 --> 01:07:50.220 of input on what to credit for, but everyone read to it. Even 899 01:07:50.220 --> 01:07:53.100 Boehner agreed if you guys do this, then you've done what you 900 01:07:53.100 --> 01:07:56.400 can on Nova for Neff. So everyone, the quarry everyone, 901 01:07:56.430 --> 01:07:59.130 all the program leaders had to agree to it. And they all did. 902 01:07:59.430 --> 01:08:03.720 And that's what we that's what was that was the program of Nova 903 01:08:03.720 --> 01:08:06.030 on ICF, in addition to the weapons program, 904 01:08:06.090 --> 01:08:10.560 and by the way, Marshall slider named the National Ignition 905 01:08:10.560 --> 01:08:12.240 Facility at that time, no, I 906 01:08:12.240 --> 01:08:14.190 didn't. I didn't like it. But he does. 907 01:08:15.300 --> 01:08:20.130 Remember sitting in his office and saying, you know, the fusion 908 01:08:20.130 --> 01:08:25.050 energy program tries to deny that it had certain goals or 909 01:08:25.050 --> 01:08:28.380 certain and that's it. This is for admission, so why don't we 910 01:08:28.380 --> 01:08:31.950 just call it that. And so it's some degree, it's Marshalls 911 01:08:31.950 --> 01:08:34.950 fault that I helped him Yeah. And I never liked it because 912 01:08:34.950 --> 01:08:37.440 either you guys be bought or wanted to change it to the 913 01:08:37.440 --> 01:08:39.240 national illumination facility. 914 01:08:40.800 --> 01:08:43.260 So if I wanted to call it like supernova or something, you 915 01:08:43.260 --> 01:08:45.780 know, because you're all the Shiva was a multi armed guard, 916 01:08:45.780 --> 01:08:50.790 you have no upgrade. I didn't want I didn't like it called def 917 01:08:50.910 --> 01:08:54.510 and I was hoping like either would become just nit, but not 918 01:08:54.510 --> 01:08:57.420 the so called the natural history sold in parentheses now. 919 01:08:57.990 --> 01:09:02.010 I was hoping to just become Neff. Man, just like everyone 920 01:09:02.010 --> 01:09:05.580 remembers eaters, international token, Experimental Reactor. 921 01:09:05.700 --> 01:09:06.840 It's It's Latin for 922 01:09:06.840 --> 01:09:07.380 the way. 923 01:09:09.000 --> 01:09:10.590 I think we had a question back here with Gary. 924 01:09:10.950 --> 01:09:11.940 And it's a good one. 925 01:09:13.980 --> 01:09:17.130 Things about the X ray lasers and how that impacted our field. 926 01:09:17.130 --> 01:09:22.230 And there's a lot of great, great stuff on FBI, but FBI 927 01:09:22.230 --> 01:09:24.990 there's obviously an enormous program to put funding into 928 01:09:24.990 --> 01:09:29.070 everything, especially the representatives. Is that do you 929 01:09:29.070 --> 01:09:34.590 have any recollection other than normal lasers take anything from 930 01:09:34.590 --> 01:09:35.910 SDI or 931 01:09:37.470 --> 01:09:42.570 something like that? I didn't I mean the the it didn't change 932 01:09:42.570 --> 01:09:45.510 the laser Well, I mean directed energy because you know that 933 01:09:45.540 --> 01:09:48.840 that was already underway. Right this was a laser was invented 934 01:09:48.840 --> 01:09:51.390 directed energy production and started actually and on the 935 01:09:51.390 --> 01:09:54.450 Naval Research Lab was very active because the Navy was 936 01:09:54.480 --> 01:09:58.020 looking for protecting ships. So they were very active in that so 937 01:09:58.230 --> 01:10:01.200 so what it what it did This is actually Bob Kraft, he has a 938 01:10:01.200 --> 01:10:06.660 good story about this illusio a lot of controversy about a deal 939 01:10:06.660 --> 01:10:10.320 about X ray, you know, using a nuclear weapon to energize an x 940 01:10:10.320 --> 01:10:12.720 ray, I remember talking to tell her about says, you're going to 941 01:10:12.720 --> 01:10:15.120 convince the Russians, the Soviets, that this is a 942 01:10:15.150 --> 01:10:18.090 defensive nuclear weapon, not an offensive nuclear weapon. And 943 01:10:18.090 --> 01:10:21.510 that's nothing that's gonna be a hard discussion. And what he 944 01:10:21.510 --> 01:10:24.480 said, this is actually true. He said, the main reason I'm doing 945 01:10:24.480 --> 01:10:28.380 this is that we need new people in the weapons program. We've 946 01:10:28.380 --> 01:10:32.970 miniaturized at, you know, we had to know the atomic bomb, the 947 01:10:32.970 --> 01:10:35.670 atomic bomb, thermonuclear weapons and miniaturization. 948 01:10:36.030 --> 01:10:38.910 We're all done. How am I going to get people interested in 949 01:10:38.910 --> 01:10:41.640 nuclear weapons and Star Wars, that was his reason we needed a 950 01:10:41.640 --> 01:10:44.400 third, we need no third generation nuclear weapons. It 951 01:10:44.400 --> 01:10:46.200 was about bringing people in the laboratory. That was his 952 01:10:46.200 --> 01:10:49.560 principal, Principal reason this was very much used to tell that 953 01:10:49.560 --> 01:10:51.630 to victory, stewardship. That's the whole thing for stewardship. 954 01:10:52.140 --> 01:10:56.160 And so it had that big impact. Bill Goldstein was hired. This 955 01:10:56.160 --> 01:11:00.240 was Rad Lab Director was basically to do atomic structure 956 01:11:00.240 --> 01:11:04.650 calculations, we actually laser. But they'll crop the Northeast 957 01:11:04.650 --> 01:11:09.120 on the phone. But Bill went to right after we demonstrated and 958 01:11:09.120 --> 01:11:14.820 published the laboratory X ray laser. Jill went to Russia. And 959 01:11:14.850 --> 01:11:18.210 this is before the paper had been come out. But it had been 960 01:11:18.210 --> 01:11:22.890 except for publication. And Bill said that we have made an x ray 961 01:11:22.890 --> 01:11:26.370 laser. And he said the Russians were surprised. And it had a big 962 01:11:26.370 --> 01:11:29.190 impact on their view of Star Wars that it was possible to 963 01:11:29.190 --> 01:11:32.130 make it work. I mean, Dolan does a wonderful story about that. 964 01:11:33.030 --> 01:11:36.000 They're in a of course, we're bragging about it. So it did 965 01:11:36.000 --> 01:11:40.770 have an impact in that sense. But it was it was one of very 966 01:11:42.060 --> 01:11:44.640 wonderful times it was really exciting when it worked. I mean, 967 01:11:45.420 --> 01:11:49.080 everyone and all it actually was a motivator for Novo one of the 968 01:11:49.080 --> 01:11:52.620 reasons no that gave as many shots we added a second target 969 01:11:52.620 --> 01:11:57.150 chamber to continue X ray laser recent research. And so that was 970 01:11:57.300 --> 01:11:59.700 so one of the reasons we got all these shots was I've had to 971 01:11:59.700 --> 01:12:03.900 target temperature them to attend beam and Jeff if you want 972 01:12:03.900 --> 01:12:03.990 to 973 01:12:04.020 --> 01:12:07.560 Yeah, there was there was another I don't know Mike, were 974 01:12:07.560 --> 01:12:12.360 involved in it. But also I saw was, was out living also had a 975 01:12:12.360 --> 01:12:16.410 program with the accelerated the ATA didn't test accelerator, 976 01:12:16.800 --> 01:12:21.810 where we were going to build a FTL but micron incredible 50 977 01:12:21.810 --> 01:12:26.160 gigawatt average power. It was gotten done once imagination, 978 01:12:26.850 --> 01:12:32.820 and it was a Brigadoon moment, I would call it where the isotope 979 01:12:32.820 --> 01:12:39.240 separation technology folks work with the ICF folks in 1985. And 980 01:12:39.240 --> 01:12:42.330 we actually built a teamwork between the two that didn't 981 01:12:42.330 --> 01:12:45.900 exist, even though even leisure programs didn't really exist 982 01:12:45.900 --> 01:12:49.560 between the two. And that last that was stick Briggs ran that 983 01:12:49.710 --> 01:12:56.640 the exercise we did. And that's how I got to know a lot of the 984 01:12:56.640 --> 01:13:00.810 laser, the John Han Citron channel really know them quite 985 01:13:00.810 --> 01:13:05.850 well, that how would Pauwels in the ICF program. So it was a 986 01:13:05.850 --> 01:13:11.190 team building exercise in the mid 80s. And that was a large 987 01:13:11.190 --> 01:13:16.530 focus of laser programs at the time, because not only was ICF 988 01:13:17.190 --> 01:13:20.610 program but we wanted to build free electron lasers back then 989 01:13:20.670 --> 01:13:21.210 also 990 01:13:22.710 --> 01:13:26.340 build I mean, if you look across this spectrum of directed 991 01:13:26.340 --> 01:13:30.060 energy, so hyper microwaves, there was massive work going on 992 01:13:30.660 --> 01:13:34.920 to do STR EO and how to use these a lot my paper microwaves, 993 01:13:35.280 --> 01:13:38.430 high rep rate, pulse power or solid state switching magnetic. 994 01:13:39.510 --> 01:13:43.560 Actually, my cousin is a nuclear physicist that the European 995 01:13:43.560 --> 01:13:47.190 atomic energies, you can research facilities in houses. 996 01:13:47.910 --> 01:13:52.230 And the European Atomic Energy Authority had a workshop during 997 01:13:52.260 --> 01:13:57.180 FDA all for this specific purpose of figuring out where 998 01:13:57.180 --> 01:14:00.600 will this take American technology? And what do we have 999 01:14:00.600 --> 01:14:04.290 to do to catch up so even independent X ray laser, it was 1000 01:14:04.890 --> 01:14:09.540 a huge technology push across many fronts. And the downside 1001 01:14:09.540 --> 01:14:12.420 was what it did, it also amalgamated a number of programs 1002 01:14:12.420 --> 01:14:15.600 that had been ongoing for a long time. And then when Star Wars 1003 01:14:15.600 --> 01:14:19.020 died, I took a few of them down with him as well, especially on 1004 01:14:19.020 --> 01:14:23.850 electron beams and but the dark accelerator at Lasala was just 1005 01:14:24.390 --> 01:14:28.890 like, you know, that electron beam was the dream of many 1006 01:14:28.890 --> 01:14:31.950 people in high intensity electron beams during Star Wars, 1007 01:14:32.100 --> 01:14:35.280 you know, 1.6 kilograms for you're gonna look like 20 Mega 1008 01:14:35.280 --> 01:14:35.640 bolts. 1009 01:14:35.700 --> 01:14:41.130 You're gonna fly that. Yeah, but the ATA construct was its new 1010 01:14:41.130 --> 01:14:46.200 ground based system uplink and, and sent down and so when we 1011 01:14:46.200 --> 01:14:51.060 exercise a lot of skills, high power skills, nonlinear 1012 01:14:51.060 --> 01:14:55.290 propagation videos, and build teams with a Brigadoon moment 1013 01:14:55.290 --> 01:15:00.120 which only lasted for that. One summer, when we worked on It's 1014 01:15:01.290 --> 01:15:04.740 helpful for me when I became the project manager. Well, one of 1015 01:15:04.740 --> 01:15:09.990 the ICF because I had built up relationships with people over 1016 01:15:09.990 --> 01:15:13.350 in the ICF program, technologists over there. 1017 01:15:14.100 --> 01:15:19.020 And it's actually one of you know, some of the ivy startups 1018 01:15:19.020 --> 01:15:21.930 will go into details but are actually touching back into some 1019 01:15:21.930 --> 01:15:25.080 of the concepts that were developed during in Star Wars, 1020 01:15:25.320 --> 01:15:28.320 or some of the scaling that may be required for distribution 1021 01:15:28.320 --> 01:15:31.500 energy as well. Great, 1022 01:15:31.530 --> 01:15:34.440 thank you very much for a wonderful session. The comments 1023 01:15:34.440 --> 01:15:38.730 were great and the Phillies were really fun to hear. At 1230 1024 01:15:38.730 --> 01:15:42.360 we're going to reconvene so after lunch and start the 1025 01:15:42.360 --> 01:15:47.100 session on stockpile stewardship petawatt and the launch of the 1026 01:15:47.100 --> 01:15:52.020 national mission facility, whereas Mike and John Zuko will 1027 01:15:52.020 --> 01:15:56.400 leave that session. So for those of us here, there's lunch 1028 01:15:56.430 --> 01:16:00.720 outside, and so you can bring it back in and have lunch and we'll 1029 01:16:00.720 --> 01:16:02.070 meet in about 45 minutes.
